Reclosable dispenser package, reclosable outlet forming structure and method and apparatus for making same.

An aperture forming structure includes a break away tip member (634) of thermoformable plastic. The break away tip includes a hollow protrusion extending from a surface. The intersection of the hollow protrusion and the surface is a fault line (636). Rupturing of the fault line creates an aperture for dispensing the contents of the package. A cap (620) may be integrally formed with the aperture forming structure and detached for protecting the hollow protrusion or for closing the aperture. The aperture forming structure can be made by heating a relatively stiff substantially flat thermoformable sheet of and then stretching the sheet to create a first and second hollow protrusion in tiered configuration. A rupture line is placed at the intersection of the first and the second protrusions. The sheet may be attached to a pouch or containment member formed from a flexible sheet which contains any flowable substance.

METHOD FOR MAKING AIRSPRING FLEX MEMBERS

METHOD FOR MAKING AIRSPRING FLEX MEMBERS A method of manufacturing a beadless flexible member for an airspring having a fully molded non-tubular shape. An axially segmented mold with tapered circular end bores is used with conically tapered end plugs which sealingly compress an uncured preform of the flexible member between the conical plugs and the tapered circular end bores. Compressed fluid is injected into the interior of the preform to radially expand it to the desired molded shape. At a rate determined by the radial expansion of the preform, the annular segments of the mold are axially moved together to accommodate the axial foreshortening of the preform during its radial expansion. After full axial closure of the mold, heat and pressure are applied to vulcanize the preform. The beadless, fully molded flexible member may be used for airsprings requiring zero pressure roll capability. Preferred forms of the flexible member have tapered wall thickness in the neck with circumferential ...
